Abstract

The invention provides a gain medium multiplexed slice hybrid amplification laser. The laser comprises a seed laser for injecting amplifier seed light. The laser beam sequentially passes through a first lens, a second lens, a first polarizing film, a Faraday rotator and a half-wave plate and then entersa regenerative amplifier. The laser beam is subjected to oscillating and amplifying in the regenerative amplifier and then enters a traveling wave amplifier through the half-wave plate, the Faraday rotator and the first polarizing film. The traveling wave amplifier and the regenerative amplifiershare a slice gain module. The invention further provides a laser output method. The device and the method are compact in structure and high in comprehensive light efficiency.

Description

technical field [0001] The invention relates to a thin slice laser amplifier, in particular to a regenerative and traveling wave mixed amplifier laser multiplexed by gain media. Background technique [0002] Thin-sheet lasers are an important development direction of high-average-power lasers. The heat dissipation characteristics of laser media are an important factor affecting the development of high-power lasers. Thin-sheet lasers use crystals with a thickness of 100-200 μm as gain media. The diamond with the highest thermal conductivity is welded, so that the heat in the crystal can be efficiently transferred to the heat sink; in addition, with the support of backside cooling technology and end-face flat-top pump light, this structure can produce , Almost uniform axial one-dimensional heat flow, which can reduce thermal lens effect and heat deposition in the gain medium, so that high efficiency and high beam quality can be maintained while obtaining high-power laser outpu...
